Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
Embodiments of the present invention will be apparent with reference to the following description and attached drawings. In the description and drawings, particular implementations of embodiments of the invention are disclosed in detail as being indicative of some of the ways in which the principles of embodiments of the invention may be employed, but it is understood that the scope of the embodiments of the invention is not limited correspondingly. On the contrary, the embodiments of the invention include all alternatives, modifications and equivalents as may be included within the spirit and scope of the appended claims.
The volume adjusting method in the embodiment of the invention is used for realizing automatic adjustment of the volume of the broadcasting terminal along with the size of the environmental noise. In practical application, the broadcast terminal is connected with a plurality of detection devices, and the detection devices are used for detecting audio signals in the environment.
Referring to fig. 1, a method for adjusting the volume of a broadcast terminal according to a first embodiment of the present invention includes steps S11 to S13.
And S11, when the broadcasting terminal is started, acquiring the audio signals in the environment acquired by the detection equipment in real time.
When the broadcasting terminal starts to play the broadcasting, the detecting device starts to work, and collects the audio signals in the environment in real time, and it can be understood that the audio signals in the environment comprise the broadcasting signals played by the broadcasting terminal and noise signals in the environment, and all sound signals except the broadcasting signals in the environment can be called noise signals.
Step S12, audio frequency separation is carried out on the audio frequency signals so as to separate noise signals, and noise energy values are calculated according to the noise signals.
Because the broadcast signal output by the broadcast terminal can be actually collected, the audio signal contains the broadcast signal, the audio signal can be subjected to signal separation, and the broadcast signal is separated out, so that a noise signal is obtained. In particular, the signal separation may be implemented by using an existing algorithm, such as a subtraction method, where the spectrum of the broadcast signal is removed from the spectrum of the audio signal by a subtraction method, and the noise spectrum is preserved. Thereby separating noise signals in the environment, and calculating a noise energy value according to the noise signals obtained by separation, wherein the calculation formula of the noise energy value is as follows:
Figure BDA0004100876730000051
wherein E is n Represents the energy value of the noise signal of the nth frame, N represents the total number of sampling points in the noise signal of one frame, S i Representing the sample value of the i-th sample point.
When the method is implemented, the force can be given to the noise signals by needle division, windowing and the like, the frame length is 20mS, when the 8KHz sampling rate is adopted, each frame contains 160 sampling points, and the square sum of the data in the frame is the noise energy value of the noise segment.
Step S13, inquiring a target output volume level corresponding to the noise energy value in a preset volume level data table, and adjusting the volume of the output signal of the broadcasting terminal to the target output volume level.
The volume level data table includes a plurality of noise energy value ranges and corresponding output volume levels. In the implementation, according to the working volume range of the broadcasting terminal and the hearing sizes of the human ears under different noise volumes, a plurality of volume levels corresponding to the noise volume value ranges are determined, and each noise volume value range corresponds to one output volume level. In general, the larger the noise energy value, the larger the corresponding output volume level so that the user can hear the broadcast sound in different noise environments.
In the implementation, the noise energy value range to which the noise energy value calculated at present belongs is queried in the volume level data table according to the noise energy value calculated at present, and then the corresponding target output volume level is queried in the table according to the queried noise energy value range. Finally, the volume of the output signal of the broadcasting terminal is adjusted to the volume corresponding to the target output volume level. So that the user can still hear the audio played by the broadcast terminal in the noisy environment.
In this embodiment, the detecting device collects audio in the environment, separates out environmental noise, calculates a noise energy value of the environmental noise, determines the noise level in the environment according to the noise energy value, queries a target output volume level corresponding to the noise energy value from a volume level data table, and adjusts the volume of an output signal of the broadcasting terminal to the target output volume level, thereby realizing the purpose of adaptively adjusting the broadcasting volume of the broadcasting terminal according to the environmental noise level.
Referring to fig. 2, a method for adjusting the volume of a broadcast terminal according to a second embodiment of the present invention includes steps S21 to S27.
And S21, when the broadcasting terminal is started, controlling the broadcasting terminal to output a broadcasting signal according to a preset volume level.
The initial moment of the starting of the broadcasting terminal is to output a broadcasting signal according to the preset volume, and then the playing volume is adjusted in a self-adapting mode according to the real-time detected environmental noise.
Step S22, acquiring the audio signals in the environment acquired by the detection equipment in real time.
The detection device collects the audio signal in the environment in real time when the broadcasting terminal is started, and the audio signal comprises the noise signal in the environment and the broadcasting signal played by the broadcasting terminal.
Step S23, audio frequency separation is carried out on the audio frequency signals so as to separate noise signals, and noise energy values are calculated according to the noise signals.
And removing the broadcast signal in the audio signal through a signal separation algorithm to obtain a noise signal, and calculating the noise energy value according to the noise signal.
Step S24, inquiring a target output volume level corresponding to the noise energy value in a preset volume level data table.
The volume level data table includes a plurality of noise energy value ranges and corresponding output volume levels. In specific implementation, a plurality of volume levels corresponding to the noise volume value ranges are determined according to the working volume range of the broadcasting terminal, each noise volume value range corresponds to one output volume level, and each output volume level corresponds to one volume level.
And step S25, determining a volume adjustment coefficient of the broadcasting terminal according to the target output volume level and the volume of the broadcasting signal currently output by the broadcasting terminal.
Step S26, judging whether the volume adjustment coefficient is in a threshold range.
Step S27, if not, the volume of the output signal of the broadcasting terminal is adjusted to the target output volume level.
Wherein the volume level data table includes a plurality of noise energy value ranges and corresponding output volume levels.
The calculation formula of the volume adjustment coefficient is as follows:
Figure BDA0004100876730000071
where k is the volume adjustment coefficient, vol 1 Vol is the volume of the broadcast signal currently output by the broadcast terminal 2 And outputting the volume corresponding to the volume level for the target.
The threshold range of the volume adjustment coefficient may be set according to the type of broadcasting terminal, and different broadcasting terminals may set different threshold ranges. When the calculated volume adjustment coefficient is within the threshold value range, the broadcasting terminal is indicated that the volume amplitude to be adjusted by the broadcasting terminal is not large, and the user is not influenced even if the volume is not adjusted, so that the system does not adjust the volume, and the broadcasting terminal continuously plays the broadcasting signal with the current volume, thereby achieving the effect of reducing the resource consumption.
When the volume adjustment coefficient exceeds the threshold range, it indicates that the volume to be adjusted by the broadcast terminal is larger, and if the output volume is not adjusted, the user is affected to listen to the broadcast information, so that the volume of the output signal of the broadcast terminal needs to be adjusted, that is, the volume corresponding to the target output volume level is adjusted.
